OK fellas, Im taking the SLI/PCIe route for my next upgrade. Ive been using the holiday system guide as a reference so I may end up with something that looks similar to the $1000 upgrade. The editors note points out that for @ $166 more you can get the dual core 64 X2 42+, however, he says if you primarily game, its not necessary. I do a lot of gaming but I also do other memory/process intensive tasks so I will be getting the dual core. Anyone here think the X2 is overkill for gaming and most routine tasks? Also, when going with SLI, is it worth it to shell out the extra jack for 2 top-of the-line 7800s or would 2 7800GTs be good to go? Thanks for any opinions.
